Beautiful drama that shows the connection between hearing and hearing impaired person. Like hearing person, every hearing impaired person is unique and different thereof it's a matter whether we try to understand their thought or merely just to understand their words

[Acting]

Definitely one of the best part from this drama. All casts acted tf out here. Shout out to my favorites Meguro Ren and Kaho. Both of them really did wonderful job conveying themselves in sign language. Their expression, gesture, and body language r perfect. Kaho is an experienced actress so I expect that much from her, but I am surprised at how good Meguro is. It's amazing how he make it so easy for viewers to tell what Sou feels just by looking at his expression. He made me smile when when he smiles and made me cry when he cries. To be able to act is one thing but to be able to do it well without speaking is definitely on another level. I hope all the casts receive deserving awards for this.

[Story]

Surprisingly, I found that story development is the weak link from this drama. The acting, directing, scoring are all beautifully done except the story line. I felt like the writer is too greedy to pack as many as life lesson in this drama it affects the plot development. I do agree that side characters r important, but to flesh out all side characters in such details requires longer episodes to make the overall story line to flow nicely, if not it makes the transition between each development choppy n rush.

I also found that minato-tsumugi relationship to be redundant. If sou-tsumugi was planned to be end up together, it's better to just focus on them from the start. There r a lot of hurdle between hearing n hearing impaired person that can be fleshed out to build their relationship instead of the cliche love triangle. Herein, minato-tsumugi relationship doesnt bring anything to the plot other than unnecessary drama.

But I am still grateful that this drama attempt to give us a glimpse about the beauty n the struggle of silent world. The other good thing is the writer has done a good job to make flawed yet relatable characters. I may not agree with what they have done but I can understand where they r coming from.

[Overall]

This drama is not perfect, but I thoroughly enjoyed watching it. Rather than romance drama, I would categorise it as slice of life. The conflict presented here was something that we may overlook before so it open up a new perspective for me. The visual n aesthetic r also very pleasing in the eyes. Overall this drama feels like a warm blanket, it gives you a calm fuzzy feeling rather than excitement
